反应堆保护系统结构与可靠性的关系

Relationship between Architecture of Reactor Protection System and Reliability

从反应堆保护系统的设计准则出发,定性分析提高系统可靠性的措施,并以目前国内核电厂中广泛使用的2种反应堆紧急停堆系统的逻辑处理部分作为分析对象,采用故障树的分析方法计算其可靠性,得到了定量化的计算结果,为后续反应堆保护系统的结构设计提供参考。

Based on the design criterion of the reactor protection system,this paper provides the analysis of measurements which improve the system reliability qualitatively,and gets the quantitative calculated results for two typical logic processing parts of reactor trip system in the way of fault tree analysis.It can be used as a reference when designing the structure of reactor protection system in the future.
